## QA Analysis Report
### Impact Summary
- Files changed: X
- Functions modified: X
- Direct dependents: X
- Indirect dependents: X
### Affected Areas
#### High Impact
1. **User Authentication Flow**
- Changed: AuthService.validateToken()
- Affects: All authenticated routes
- Risk: High - Could break login
2. **Order Processing**
- Changed: OrderService.calculateTotal()
- Affects: Checkout, invoices, reports
- Risk: High - Financial impact
#### Medium Impact
[...]
#### Low Impact
[...]
### Test Strategy
#### Unit Tests Required
| Component | Tests Needed | Priority |
|-----------|--------------|----------|
| UserService.create | 5 | High |
| AuthService.validate | 8 | High |
| ... | ... | ... |
#### Integration Tests Required
| Flow | Tests Needed | Priority |
|------|--------------|----------|
| User registration | 3 | High |
| ... | ... | ... |
#### E2E Tests Required
| Scenario | Priority |
|----------|----------|
| Complete checkout flow | High |
| ... | ... |
### Test Specifications
#### UT-001: UserService.create - Valid Input
- **Type**: Unit
- **Priority**: High
- **Given**: Valid user data
- **When**: create() is called
- **Then**: Returns created user with ID
- **Edge Cases**:
- Duplicate email
- Missing required fields
- Invalid email format
#### IT-001: User Registration Flow
- **Type**: Integration
- **Priority**: High
- **Given**: New user data
- **When**: POST /api/users
- **Then**: User created, email sent, returns 201
### Recommended Test Order
1. Unit tests for core changed logic
2. Integration tests for affected flows
3. E2E tests for critical paths
### Estimated Test Count
- Unit: ~X tests
- Integration: ~X tests
- E2E: ~X tests
